A novel method predicts cancer and immune cell types from bulk tumor gene expression data with the ability to consider uncharacterized and possibly highly variable cell types, which is validated in human genome.
Nutrient limitation elicits differential responses in cells lacking the tumor suppressor PTEN and in normal cells, resulting in hyperplastic overgrowth of PTEN mutant tissue independent of additional mutations.
Tumor immunogenicity is quantified with a novel method, and the resulting tumor immunogenicity score is an effective tumor-inherent biomarker for prediction of response to immune checkpoint inhibitors.
In addition to its role in regulating proliferation and cell death, the PTEN tumor suppressor regulates epithelial morphogenesis through the PDK1 kinase.
Sestrin2 loss could be a universal mechanism of human colon carcinogenesis that allows for barrier dysfunction, mTORC1 hyperactivation, unrestricted tumor growth and chemoresistance.
Disrupting extrusion, a process that drives epithelial cell death, leads to increased cell survival, poor barrier function, and enhanced cell invasion and, thereby, promotes tumor initiation and progression.
A library of the paired peptide/HLA multimers and artificial APCs allows for construction of a large database of class I-restricted peptides and cognate tumor-reactive TCR genes at an unprecedented scale.
The forces that multicellular tumor aggregates exert on their environment lead to non-linear, scale-invariant tissue deformations far away from the tumor, which can be exploited to quantify its collective contractility.
